Swap, anyone?

I've never hosted a swap before. And I'm not absolutely sure I'm going to follow through at this point. I would be interested in feedback. If you're interested, do you want to do one big package or several small ones? Do we want to make it secret or not? What should the price range be?

I'm thinking we should swap cool and comfortable yarns (cotton, linen, bamboo, etc), things for cooling off and things for cheering up.
